T all whom it may concern: 7

Be it known that I, WILLIAMA P. WOOD, a citizen of the Unitedstates, residing at Pawtucket, in the county of Providence and State of R-hode Island, have invented certain new and useful Improvements in Winding-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will en- 10 able others skilled in the art to .which it appertains to make and use the same. 7

The invention relates to bunch building mechanism for winding ,machines such as are used for winding yarn on shuttle bob-' bins.

Bunch building mechanism of this character as usually constructed is provided with a yarn controller finger which shouldv be moved by the operator into position to engage the yarn between the traverse yarn guide and the bobbin when starting the winding of a bobbin. If the operator fails to properly set the controller finger when starting the machine, abobbin will be wound .25 without the bunch requisite for avoiding defects in the cloth woven by the loom in which the bobbin is to be used. This is a serious objection to the mode of operation of the bunch building mechanisms, and frequently 30. results in defective fabric and loss due to carelessness on the part ofthe winding machine operators. I

It is the'object of the present invention to insure the'proper and uniform building of the bunchbythe bunch building mechanism, so that the winding of defective bobbins, due to carelessness onthe part of the operator,'is prevented. To this end theinvention contemplates so controlling the winding mechanism that it cannot operate to wind the bobbin unless the bunchbuilding mechanism has been adjusted or. set to build the bunch at the beginning of the winding operation. This insures the proper setting of the bunch builder at tliebeginning of each winding operation and the building of a bunch upon every. bobbinlwound on the machine. The winding mechanism is preferably .thus ..controlled by providing means which, upon the stopping ofthe a,- chine at tlie completion of a bobbin, will retain the stop mechanism of the machine in stopping position until the yarn controller finger of the bunch building-mechanism is moved by the operator into active position Specification of Letters iatent. Sept. 14,1920.

atthe beginning of the succeeding bobbin. It; isde sirable" that this mechanism should be m aiweuunn the winding of abobbin, so that, it will notinterfere with. the normal operation of the stop, mcchanism, and should again become active at the beginning of the upon thesucceeding bobbin. Means is therefore provided .throughwhich the insertion and removal of the bobbin. controls the action oflthe means-.wh-ich inturn contr olsi th e" starting of, the winding mechamsm. I V

, The preferred form of the invention is shown in the accompanying drawings embodied in the bunchbuilding mechanism 7G shown and described in application Serial No. 242,674:, June 29, 1918. In the drawings, Figure 1 isv a plan view showing so much of a winding machine as is necessary to illustrate the application of the present 7 5 invention thereto; Fig.2 is a side elevation of parts shown in Fig. 1;.-Fig. 3 is a'similar view showing some of the parts in different position and;-Fig.- 4 isasectional eleva tion. V so In the drawings the inventionis shown applied to the well-known'Universal winding machine for -winding bobbins such as are used in automatic looms. As shown,the winding spindle 2 is provided withthe cen- 5. ter 4 and the lugs 6 for engaging the end of the bobbin. The outer'end of-the, bobbin is engaged by. the spring-pressed support 8 whichvmay be forced back in the bracket 10 in inserting and-removing the bobbins. The yarnv is guided during-the windingof the bobbin by a traverse yarn ide 12 mounted on-the reciprocating traverse bar 14:; The driving mechanism for the machine is thrown intoand out of operation by a starting rod 16 which is rocked by the operator to throw the driving mechanism intooperation, and which is latched in driving position by alatch lever 1 8 arranged to engage an arm 20 projecting from .9 the rod. vWhen the latch is disengaged from thearm the rod is rocked to; throwiout the driving mechanism and stop the 1 machine. through a spring (not-shown). The machine 1s automatically stopped upon break 5 age of the yarn througha lever 22, one arm of which is provided with an eye through which the yarn leads, and the other arm of which is provided with a lug 24E arranged to. engage a lever- 26 which is pivoted on 0 machine.

the latch 18, and is provided with an arm bar." During the operation the tension on the yarn holds the lever 22 in the, position indicated in Fig. 4, so that the arm 28 of the lever 26 is out of the path of the collar 30, When the tension on the arm is relieved,

as by the breaking of the yarn, the lever 22 will swing about its pivot, and thelug 24 wi1l rock the lever 26 so that'its'arm 28f wil'l becarried up into the path of the collar -30. When this occurs the collar 30 will,--du'ring reciprocation of the traverse bar, j strik,e the arm 28 and disengage the latch '18 from the arm 20 on the starting rod, so that the rod will be released and the machinewill be stopped. v As thus far;desc'ribed,'the machine is the sameinconstruction and mode of-operation as the"well-knownuniversal winding The, bunch buildingmechanism shown in the drawings comprises a vyarn controller finger32which' is normally retained in retractedinactive position, 'as indicated in Fig'l -l, by a spring 3 1. At the beginning of the winding operation this finger is moved forward into the position indicated in Fig. 4, so that it will engage the yarn leading from the traverse yarn guide to the bobbin, and will cause the'yarn tobe Wound in the form of a bunch withirrth'e groove 36 in the bobbin. The controller finger' is retained in active position by a vertically movable latchba r 38 which is forced upward'by the 'sprin'gf lO, and is provided at its lower end with a transverse arm 42 carry ing the contact screw 14 arranged to be engagedby the bunch of yarn'built up in the ro veee. i XVhen the bunch has been woundto the size determined by the adjustment ofjthecontact screw, it'will force the latch bar 38 downward until thefinger 32 is released, when the finger 'will'be retracted into its inactive position byits spring 34, and inwthis movement act on'the' cam shaped" upper endof'the latch'bar to press it down ward and remove the contact screw Mqfrom engagement with the yarn during the con-' tinued'winding of the bobbin. i j In applying the present invention to the winding machine and bunch building mech-' anism' above described, means is provided whichis' rendered active upon the removal eta bobbin for retainingthe stop mecha- IllSni'ill stopping position until the yarn controller finger has been moved into active pQSltlOn." In the constructionishown, this means consists of a vertically movable latch bar 16 adapted to slide in guide-ways formed in the arms of a bracket &8, and arranged to engage a shoulder 50 formed on a collar '52; which is securedto the lever 220i the 'stop mechanism; The latch-bar bar &6.

is forced downward in a direction to en gage the shoulder on the lever 22 by a spring 54, and is raised into inactive position against the tension of the spring by the engagement of the arm 42 of the latch bar 38 with a pin 56 which projects from the latch I The upper end of the bar 46 is slotted at 58 to form a hook 60 adaptedto overlieandengage the upper arm of the bracket 48 when the bar is in its raised position, and to support the bar with its lower end out of active position. The spring 541- tends-to draw the upper end of the bar laterally' into 1 position 'for its hooked end to engage and rest on thearm of the bracket. Movementor the upper end of the bar into this position is prevented whenever there is no bobbin inthe machine by a plate 62 mounted on the end of the winding spindle 2 and pressed forw'ard'into engagement with the head of a screw 64 on the bar 46 by the springs 66; When a bobbin is in position' inthe-machine, it presses the plate 62 back, as indicated in Fig. 3, so that the spring 54: is free to draw the upper end of thelatchbar 46 into position to engage and be retained by the I upper late of the bracket 48. r a 7 v r 7 Assuming that a bobbin has been'inserted, and the controller finger -32 moved into position, and the machine started,-to begin the winding of the bobbin, the parts will be in the'position indicated in Figs. 8 and L As the-winding continues, the controller finger will; guide the yarn into thegroove36 until the-bunch built therein depresses the latch bar 38 and releases the controller finger. When this occours, the arm/l2 of the latch bar38 will move down away from the pin '56, andthe latch bar 46will move downward until the hook 60 at its upper-end rests on the upper plate of the bracket 48, where it will remain until the winding of the bobbin has been completed and the machine has been automatically stoppe'd'by the usual mechanism. hen the bobbin is removed, the plate 62' -will move forward into the position indicated in Fig.=' 2, andin'so doing will engage the screw 64 and disengage thefhook '60 on; the bar 4e61from its sup-' portingarm, thus permitting the bar to move a down into position to. engage the shoulder 50 on the lever 22 of the stop mech- 1 anism, this leve'rhaving movedfover into stopping position when the tension on the yarn was relieved. The latch bar 46 will now lock the stop mechanism in stopping position until the. controller finger 32 is swung into active position atthe beginning of the succeedingwindingoperation after a fresh bobbin has been, inserted in the machine. When the controller finger isv moved into active position, the upward movement ofthe latch bar 38 and its arm 42 will disengage the-:latchbar 46 from the lever 92-2, so that the lever may move into latch bar lGto active. position will be prevented bythehook 60 at its upper end until the winding of this bobbin has beencom pleted and the bobbin is removed. The latch bar will not therefore interfere with the normal automatic action of the stop mechanism during the winding of the bobbin, but will prevent the starting of the winding upon a fresh bobbin until the bunch building mechanism has been properly adjusted by the operator. I

lVhile theinvention has been shown and described as applied to the bunch building mechanism of the application above referred to, it will be understood that it is not confined in its application to this bunch building mechanism, but may be applied to other forms of bunch building mechanism. It will also be understood that while it is preferred to employ the specific construction and arrangement of parts in applying the invention to the bunch building mechanism shown and described, this construction and arrangement is not essential to the broader features of the invention, but may be varied or modified as found desirable or best suited to the construction and arrangement of parts in the winding mechanism and bunch building mechanism to which it is to be applied.
